“Aizver muti!” is a quotable one-liner by Ingmārs Līdaka, at that time a deputy of the 9th Saeima (Latvian Parliament)…

…On October 15th, 2009, during a regular meeting of Saeima, Līdaka climbed on the tribune to comment on the proposed reduction of days when you have to hoist a Latvian flag on your house. Although he seemed calm, if a bit tense at start, he soon became angry when he mentioned that he heard the “left wing” talking about removing 11th (Lāčplēsis Day, meant to honour the fallen soldiers in the Independence War of 1918–1919) and 18th November (Latvian Independence Day) out of the calendar of holidays…

…While explaining that the Independence Day is a holiday in all countries, he heard the “left wing” (Harmony Centre and ForHRUL) politicians talking and shouted “Aizver muti!” (Shut your mouth!) mid-sentence.
